That’s kind of the confusing thing for me, I wouldn’t have a human personal assistant do anything for me as long as any money is on the line. I couldn’t teach them my preferences well enough to trust them to do it the way I want, instead of just doing it myself.
Personal assistants only make sense to me if you’re so rich that money doesn’t really matter to you anyways.
Your trip booking thing for example is something I would never give to a human assistant.
